It’s a pity you didn’t take my original post back in December 2022 more seriously - I didn’t even get an acknowledgement from the devs.
I would have been more than happy to assist with code testing on my machine, like I did with Oz way back when we established basic support for the Snapmaker 2.0.
Like others I have been patiently waiting for a ‘fix’, which your latest update is not. Whilst the B axis is now present in the code, the moves are not even remotely correct. It should contain Y moves and B rotations as is the case for the Luban software output I listed in the OP.
